Subproblem 1

Set the factor '(10 + -5x + 2x2)' equal to zero and attempt to solve: Simplifying 10 + -5x + 2x2 = 0 Solving 10 + -5x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 5 + -2.5x + x2 = 0 Move the constant term to the right: Add '-5' to each side of the equation. 5 + -2.5x + -5 + x2 = 0 + -5 Reorder the terms: 5 + -5 + -2.5x + x2 = 0 + -5 Combine like terms: 5 + -5 = 0 0 + -2.5x + x2 = 0 + -5 -2.5x + x2 = 0 + -5 Combine like terms: 0 + -5 = -5 -2.5x + x2 = -5 The x term is -2.5x. Take half its coefficient (-1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. -2.5x + 1.5625 + x2 = -5 + 1.5625 Reorder the terms: 1.5625 + -2.5x + x2 = -5 + 1.5625 Combine like terms: -5 + 1.5625 = -3.4375 1.5625 + -2.5x + x2 = -3.4375 Factor a perfect square on the left side: (x + -1.25)(x + -1.25) = -3.4375 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
